Abstract: A cellular network includes multiple miniature base stations. The miniature base stations are communicatively connected to each other. Each one of the miniature base stations includes an antenna, a wireless signal transceiver and a digital signal processor. The antenna is arranged at a peripheral area of the miniature base stations and configured to receive and to transmit wireless signals. The wireless signal transceiver is configured to demodulate the wireless signals received from the antenna and to modulate the wireless signals transmitted by the antenna. The digital signal processor is configured to process the wireless signals, which are demodulated or modulated.

Abstract: A method includes the following steps. A wafer is disposed on a wafer-mounting surface of a wafer holder that is disposed in a chamber. The wafer-mounting surface is in parallel with a gravity direction. A gas is flown from a gas source to vacuum sealing device. An inductive coil wrapping around a vacuum sealing device excites the gas into plasma. The plasma is injected to the wafer.

Abstract: The present disclosure provides an alert device and an alert method. The alert device includes an image capturing unit, an input/output unit and a processing unit. The image capturing unit is configured to capture at least one image of a wafer transportation system. The processing unit is configured to: retrieve the at least one image from the image capturing unit; define a first boundary in the at least one image; identify a wafer chuck of the wafer transportation system in the at least one image; determine whether the wafer chuck intersects the first boundary in the at least one image; and transmit an alert signal to the wafer transportation system via the input/output unit when the wafer chuck is determined to intersect the first boundary in the at least one image.

Abstract: The present disclosure provides a wafer cleaning apparatus and a cleaning method. The wafer cleaning apparatus includes a tank and a wafer holder. The tank includes a bottom wall, a lateral wall, and a partition wall. The lateral wall is connected to the bottom wall. The partition wall is movably mounted on the lateral wall and divides a cleaning space defined by the bottom wall and the lateral wall into a first compartment and a second compartment. A passage communicating with the first compartment and the second compartment is formed when the partition wall is moved away from the bottom wall and immersed in a cleaning fluid received in the cleaning space. The wafer holder is adapted to be immersed in the cleaning fluid and to move between the first compartment and the second compartment. The present disclosure further provides a method of cleaning the wafer.

Abstract: A device includes a wafer chuck, a first nozzle, an actuator, and a first elongated cup. The first nozzle is disposed over the wafer chuck.
